METHOD FOR PRODUCING TEMPLATE-TEXTURED MATERIALS WITH HIGH BINDING SPECIFICITY AND SELECTIVITY AND UTILIZATION OF SAID MATERIALS

The invention relates to a method for the production of a template-textured material by synthesis of a template-textured polymer (TGP) by performing crosslinking polymerization of functional monomers on a carrier in the presence of a template. The invention is characterized in that a carrier having a thin polymer layer on the surface thereof is modified with a reaction mixture consisting of a polymerization initiator, a template, a functional monomer, a crosslinking agent, a solvent and/or a buffer. Polymerization is initiated after the reaction mixture has been absorbed in the thin polymer layer and continued until the absorption capacity of the thin polymer layer for the template-textured polymer (TGP) is achieved. The template is then optionally removed during a final step. The carrier used is selected in such a way that it cannot absorb the reaction solution. The materials disclosed in the invention are characterized by high binding specificity and selectivity for the template.

Method of making ionic liquid mediated sol-gel sorbents

Ionic liquid (IL)-mediated sol-gel hybrid organic-inorganic materials present enormous potential for effective use in analytical microextraction. One obstacle to materializing this prospect arises from high viscosity of ILs significantly slowing down sol-gel reactions. A method was developed which provides phosphonium-based, pyridinium-based, and imidazolium-based IL-mediated advanced sol-gel organic-inorganic hybrid materials for capillary microextraction. Scanning electron microscopy results demonstrate that ILs can serve as porogenic agents in sol-gel reactions. IL-mediated sol-gel coatings prepared with silanol-terminated polymers provided up to 28 times higher extractions compared to analogous sol-gel coatings prepared without any IL in the sol solution. This study shows that IL-generated porous morphology alone is not enough to provide effective extraction media: careful choice of the organic polymer and the precursor with close sol-gel reactivity must be made to ensure effective chemical bonding of the organic polymer to the created sol-gel material to be able to provide the desired sorbent characteristics.
